I bought Jupiter Dimedici 1011 for my 12 year old son who plays for the local Youth Symphonic Orquestra. The instructors (one of them has a flute doctorate from one of our universities and vast teacheing experience and myself agree that this is a great instrument. Smooth response, warm and steady tone, really well built and also beatiful. We compared it with the orchestra's two Armstrong and three Yamahas and we think it plays better than all of them. The tone is much better than the Armstrongs and can be compared with the Yamahas' but it has a superiror proyection power.
